Toxic! Just like #Trump!
Dead ducks add to Trump’s reflecting pool drama
A local wildlife organization is performing necropsies on ducks found dead near the Lincoln Memorial Reflecting Pool.
Excerpt: "A local wildlife organization collected two deceased ducks, found at a pond adjacent to the pool Sunday. The same day, a Washington Examiner journalist documented another dead adolescent duck floating in shadow of the Lincoln Memorial. The presence of deceased waterfowl has sparked speculation of #ToxicAlgae, sometimes known as blue-green algae, or #cyanobacteria, in the lime-green gunk that swiftly proliferated after the Trump administration installed a commercial pool liner earlier last month."

There is nothing so special about this time, seen from the perspective of an immortal. Anything has happened before. Earth doesn't need us.
The only new thing us that humans, in contrast to the #cyanobacteria of the #GreatOxidationEvent, were conscious: -

#ClimateCatastrophe
#ExtinctionLevelEventYes, the only other species known to me to have ever been so stupid as to have destroyed their whole biosphere on a global level, are #cyanobacteria in the #GreatOxidationEvent in the #Paleoproterozoic Era.
2.4 billion years and #humanity collectively has an #IQ of these ancient bacteria.
Maybe, it deserves to become extinct?
Cheers!

#ClimateChange Contributes to Shift in #LakeErie’s Harmful #AlgalBlooms
Blooms over the past decade have started earlier in July and had longer peaks, according to #NOAA researchers.
By Kathiann M. Kowalski
July 26, 2024"Lake Erie’s harmful algal blooms have started sooner and had longer peak periods over the past decade compared to earlier years, newly released data shows. Warming temperatures linked to climate change are a cause, according to researchers for NOAA’s National Centers for Coastal Ocean Science, with interactions among species likely playing a role as well.
"The NOAA scientists discussed the shift and forecast a moderate to above-moderate algal bloom for the lake’s western basin this summer during a briefing last month at Ohio State University and Ohio Sea Grant’s Stone Laboratory, off the coast of Put-in-Bay on Lake Erie.
"Algal blooms occur when #cyanobacteria, or blue-green algae, grow out of control due to a combination of excess #nutrients, #weather patterns and other #ecological factors. The blooms can be a serious public health problem because some types of cyanobacteria produce toxins. #Microcystin, for example, can lead to skin rashes, gut problems and liver and kidney issues. Relatively high levels of it in August 2014 prompted a two-day shutdown of #Toledo’s public #WaterSupply, which comes from Lake Erie."

Algal Toxins and Wildlife Health
By National Wildlife Health Center September 30, 2019
"Harmful #AlgalBlooms (#HABs) have the potential to harm fish and wildlife, domestic animals, livestock, and humans through toxin production or ecological disturbances such as oxygen depletion and blockage of sunlight.
"To investigate the effects of algal toxins on wildlife, the USGS National Wildlife Health Center (NWHC) has examined over 300 dead animals collected during freshwater and marine #HAB events since 2000. Varying levels of algal toxins were found in over 100 of these animals. In some cases, the history, clinical signs, and high toxin levels have allowed scientists to attribute mortality to algal toxicosis. Recent events have included Kittlitz’s #murrelets (Brachyramphus brevirostris) in Alaska that died after consuming sand lance (Ammodytes hexapterus) high in #saxitoxin (Shearn-Bochsler et al. 2014), #GreenTreeFrogs (Hyla cinerea) in Texas with suspected #brevetoxicosis in association with a #RedTide event (Buttke et al. 2018), and #LittleBrownBats (Myotis lucifugus carissima) in Utah found dead during a HAB event at a reservoir commonly used for recreation and as a source of municipal #DrinkingWater (Isidoro-Ayza et al. 2019).
"In other cases, algal toxins have been detected in wildlife, but their contribution to mortality remains unclear. Part of the reason these detections have been difficult to interpret is that the toxic dose of many algal toxins in wildlife species is unknown and the microscopic lesions (if any) particularly in birds, have not been well described. To better understand the effects of these toxins the NWHC is conducting laboratory exposure trials to determine the lethal dose of toxin in birds and to examine the repeated exposure of waterfowl to sub-lethal toxin ingestion. In addition to exposure trials, NWHC is undergoing a retrospective review of previous detections of algal toxin from NWHC’s case archives to examine demographic, spatiotemporal, and diagnostic features associated with wildlife exposure to algal toxins."

"The presence of a gelatinous surface microlayer film had been proposed in 1983, based partly on observations of the slick associated with blooms in the #SargassoSea of the filamentous #cyanobacteria #Trichodesmium... What about the ocean surface film from the #microbial neustonian point of view? It might appear to be an immense #biofilm stretching from horizon to horizon... Estimates of its thickness range from 1 to 50 µm"
